A fuel injector delivers fuel into the intake in a precise, atomized pattern; over time the pintle, coil, or spray tip can wear or clog. Diagnose the cause before replacing, as these symptoms can have other sources. If the original injector is faulty, this TJ13 replaces it to keep fuel delivery controlled and consistent.

Manufacturer part number TJ13.
